Hey, I have some buttons and 7-seg display like that too! I would take a picture of it, but my reference 6870 is literally right next to it being in the 2nd to bottom slot so I can get two full 16 lanes of PCI-E goodness.

Actually, I find that I don't need to check the 7-seg often because the CPU_LED, DRAM_LED, and VGA_LED tends to tell me enough about what is going on if the machine is having trouble booting.
